This measure can be claimed if the project improves the U-value, which indicates the thermal performance, of any of these elements of the building:
- Exterior walls
- Internal walls
- Floor slabs
- Roof slabs, and
- Window Glass
The actual U-values of the respective elements should be entered in the software in the Energy tab. For multiple element types with different U-values, use an area-weighted average.
Note: For exterior walls or roofs with insulation, the measure for ‘Wall Insulation’ or ‘Roof Insulation’ should also be selected in the Materials tab, and the actual insulation type and thickness entered.
Intention, Approach/Methodologies, Potential Technologies/Strategies, Relationship to Other Measures, Assumptions
For details on the above, see similar measure descriptions for Insulated walls, Roofs, Low-e coated glass, and High-performance glass previously described in this user guide.
This measure has several components. To claim any component of this measure, it is necessary to demonstrate that the U-value of that component is better (lower) than the base case as listed in the Key Assumptions for the Base Case in the Design section. If the EDGE default for the improved case U-value is used, then it is only necessary to demonstrate that that component has been or will be installed, and that the U-value of the component does not exceed the base case.
If a user-input U-value exceeds the default improved case value, then it is necessary to confirm that the U-value has been calculated in accordance with the “simple” or “combined” method as previously described in the Approach/Methodologies of related glass and wall measures above.
|Design Stage||Post-Construction Stage|
At the design stage, the following must be used to demonstrate compliance:
At the post-construction stage, the following must be used to demonstrate compliance:
Since insulation material will not be visible at the post-construction stage, it must be demonstrated that the insulation material specified at the design stage was delivered to the site. The following must be used to demonstrate compliance:
